                 }
             }
         }
         stage("quality gate"){
            steps {
                 script {
                     waitForQualityGate abortPipeline: false, credentialsId: 'Sonar-token' 
                 }
             } 
         }
         stage('Install Dependencies') {
             steps {

    Add DockerHub Username and Password under Global Credentials

    Add this stage to Pipeline Script

    ```bash

            stage("Docker Build & Push"){
                steps{
                    script{
                       withDockerRegistry(credentialsId: 'docker', toolName: 'docker'){   
                           sh "docker build -t zomato ."
                           sh "docker tag zomato sevenajay/zomato:latest "
                           sh "docker push sevenajay/zomato:latest "
                        }
                    }
                }
            }
            stage("TRIVY"){
                steps{
                    sh "trivy image sevenajay/zomato:latest > trivy.txt" 
                }
            }

You will see the output below, with a dependency trend.

Step 7 — Deploy the Image using Docker

Define Deployment Stage: Add a stage in the Jenkins pipeline to deploy the Docker image to a container.

 stage('Deploy to container'){
      steps{
             sh 'docker run -d --name zomato -p 3000:3000 sevenajay/zomato:latest'
           }
       }

Run Container: Use Docker commands within the pipeline to run the container with the deployed application.

stage view

<Jenkins-public-ip:3000>

You will get this output

Step 8 — Terminate the AWS EC2 Instances

Complete Pipeline Execution: Once the deployment is successful, complete the pipeline execution.
Terminate EC2 Instances: Access the AWS EC2 console and terminate the instances created during the deployment process to avoid unnecessary charges and resource consumption.
